A Heat Advisory covers most of the Tennessee Valley for Thursday afternoon and evening. Drink plenty of water and limit outdoor activity or take breaks if possible.

A late season heat wave will peak this week, with temperatures soaring well into the 90s for most locations. Heat indices will climb into the 100s. Heat is one of the leading weather-related killers in the US! Take hot temperatures seriously, drink plenty of water, find A/C, and remember to look before you lock when exiting vehicles.

Heat wave in full effect through Friday. Heat index values will reach or exceed 100 each afternoon across nearly all of the area outside of the higher elevations. Isolated to scattered thunderstorm chances begin to return on Friday, with higher chances over the weekend.
